8 Claims. (Cl. 14S-106) This invention relates to. the treating of food; and has for one of its objects the provision of a machine which may act upon the food in a manner to better prepare the same for handling while 5 being eaten.

Another object of the inventionis the provision of a frankfurter sandwich which may be more readily handled while being eaten.

Another object of the invention is the provision l of amachine which Will provide an opening in a roll or the like for the reception of an edible lling and at the same time provide an access to this opening so that the filling may be convenientlyrinserted therein.

15 Another object ofthe invention is the provision of a machine which will convey the material to be removed from the roll by the minimum amount of power and handling operations.

Another object of the invention is the pro- 20 Vision of a means for boring and at the same time extracting through the boring implement the borings which are formed up and then disposing of these borings by conveying them to a y desired receptacle or location.

25 Another object of the invention is the provision ofra carriage for guiding the Work While being operated upon by which the roll may be conveniently gripped and held in position and yet quickly and easily released when kthe carriage is retracted to position.

Another object of the invention is to` provide a means by which a roll may be bored and at the same time'slit so that it may thereafter be conveniently lled and eaten.

35 A further object of the invention is the pro- Vision of a carriage which as it is being actuated also actuates a slitting device extending into the bore of the work.

A still further object of the invention is the 40 arrangement of the parts so that vthe cutter is protected against accidental contact with the person.

With these and other objects in view, the invention consists of certain novel features of 45 construction, as will be more fully described, and particularly pointed out in the appended claims.

While this machine is adaptable for many uses, one of the uses which I have particularly in mind 10 is for the serving of frankfurters. Frankfurters are usually served by slitting a roll with a knife and inserting the frankfurter in this slit, and mustard, pickle or some dressing is then placed onv the frankfurter vin the roll. The halves of the roll flare outwardly to considerable extent by reason ofthe position of the frankfurterbe-Y tween the halvesrin this position, and when one bites into such a sandwich, the frankfurter is very liable to slip about and the mustard or dressing squeezed out upon the hands or clothing, and even with the greatest care a sandwich of this character is dilcult to manage or handle. This invention has to. do with the making of a bore invor hole through the roll of a size to receive a frankfurter and to -split the frankfurter from its top edge towards the hole so that it may be opened up,fthe frankfurter and dressing placed therein, andi' then completely closed about the frankfurter so that one may hold the sandwich in closed position and prevent the frankfurter from slipping about and the dressing on the frankfurter being squeezed out whena bite is taken; and I have provided a machine by which bothrthe boring and slitting operations may be accomplished at the same time by merely placing the roll into the carriage provided for it and manually sliding this carriage forwardly a distance substantially the length of the roll and then retracting it; and the following is a detailed description ofthe present embodiment of the invention, illustrating the preferred means by which these advantageous results may beaccomplished:

With reference to the drawings, I0 designates a 45 base upon which I have mounted a motor I I with its armature shaft I2 protruding from one end. Adjacent this motor, there is provided a fan casing I3 containing a suction fan I4 mounted upon the armature shaft I2 to rotate therewith, while 50 protruding from this casing I3 I have provided a vrigid tube I5 which communicates with the fan chamber and which serves to convey air and such Vparticles as may becarried bythe air through the tube I5 and discharge it through the 55 opening I6 from the fan casing. A shaft II is xed to the armature shaft I2 to rotate therewith and to extend longitudinally through the tube I and is pointed at its outer end I8 for the purpose of piercing the Work and directing the path of travel of a cutter member. A helical groove in this tapered end may serve to assist in its operation.

The cutter member is designated generally I8 and comprises a tubular body 20 which is suitably securedto the shaft fI'I. The zbody :20 extends along the tube I 5 and 'is provided With ballbearings 22 to guide the cutter I9 in its rotation. The cutter I 9 is provided with a pair or more of cutting blades 23 the leading edge portion 'of reach blade having a serrated cutting edge which serves to chew up into ne particles vthe `materia-1 through which it is passed, ;and these Ifine `,particles are sucked by the fan I4 through the tube I5 and discharged from the fan casing I6 iin'to asuitable container for them.

Positioned on .the .base .I0 and .projecting .beneaththe tube I5, I have ,provided a platform 25 .supported yby legs, ...and ,upon .this ,platform is mounted a. pair of guide rods 26 .constituting a .track whichaslidably mounts .a carriage 2'I having .abottem ,Wall 28, end .Walls .29 Cand 3,0 with central slots or openings 3|., .32,33 ,therethrough for the `passage of. the .cutting implements, while a side wall :Slisxed -to the .bottom wall and end Walls along :one side .of .the bottom W..all. Also on this `fbottom wall there 4are provided bearings 35 -for the .reception of the guide .rods `or .tracks .26. The .carriage ;a1so includes -a sidewall 36 which, 4itse1f,`has bearings 3.'I hingedly mounted upon one .ofthe side rods 2.6 .and located between the slide bearings .35. This wall is-of ashape comparable .to its-.opposite wa1l=34.and.is,provided with vpro-- Jections 3.8 4tofextend `intoslots 39 in :theend Walls .of fthe .carriage to ,limit the inward swinging Ymovement of .theside .wall 36,. Itis desirable that V.this :side wall .shall tswing outwardly when .releasedso that its fnormal zposition will be such as .illustrated in Figure y9; .and .in .order that this .may be. accomplished, .I have `provided .a spring MI xencirclingfoneof -the rods 26 and held in .posi- .tion :by having its 1ends project Ainto openings v:one in `the side 36 :and the other ,-in .the .bottom .2.8, vthere .being ,a 'tension on the spring tending ,to .swing .theside .vvall .about one of the rods as an .axis into a .positionsuch as illustrated in Figure r4 .or Figure .9 ;and .this wal-1 .is .limited in `its-outward `swinging .movement by :movement Yof .the :stop-A3 ,provided thereon. Y

.I shave 4termed a.s1ot 45 in .the middle ofthe platform 2,6 .in which is mounted ,axcrcular disc .or .cutter 4.6 -upon .shaft 4,1 ,having bearings-in -the `:platform 2.5. Fixed `to 'this cutter, either directly Ior through the sha-tt '41 I have provided @a spur ,gear 8 whichengages yvitha rack lfxed .on the .carriage .so that as this .carriage is -slid.alon g the rods .-26, :fthis .cutting disc 46 will be rotated .to slit .the roll by reason of its movement through the slots 32,133 ,of -thecarriage.

IIn operation, :it is -merely necessary to drop a roll with :its top vdownward into .the fcarriage., Vgrasp the 'sides :of .the .carriage 34 .and 36 ,and swingfthe side 36 inwardly fsufliciently'to ,gr-ip the ,roll :and hold it in position, 4and then Aslide the .caimiage tierwardly towards the fmotor .which is running .to .operate -thefcutter to -bore `a hole .through .the roll-and at .the .same'time slit rthe roll :50 :as at l5.I,.see Eigu-re f7.. The .opposite ends of the strokepfzhe-,carriage ,are cushioned .by resili- .ent Iabutments f5.0 atfone end and -6I at'the other.

After the carriage is retracted, the sides may be released, the roll picked out, spread apart, and the frankfurter 52 with the dressing 53 placed thereon, and the roll then closed to securely hold the frankfurter and dressing in position. At the same time as this boring operation takes place, the particles which are removed to form the hole through the roll are chewed into ne bits, and these borings are sucked out by the fan and deposited in a receptacle so that they do not fly about or accumulate in the area about wvhich the machine is mounted.

The ends of the carriage are thickened as at 63 and the stroke of the carriage so arranged that `thexqutter -I-.9 will locate therein at each end of its stroke and be housed so that danger of accidental rContact with the rotating cutter will be reduced to a, minimum.

This device may be operated quickly and eiiicient1y,and the serving of the frankfurter material .is enhanced.

.The foregoing description .is .directed solely `towards the `construction illustrated, but I desire it tobe understood that .I .reserve the `privilege of resorting 'to all the mechanical changesV to which the device .is susceptible, .the invention .being .fdened and flimited only .by .the terms .of the appended claims.
